The heaviest element in this group was synthesized by bombarding californium with calcium. The textbook example of a molecule with square planar geometry involves four fluorines bound to an element in this group. Ununoctium is technically a member of this group, which contains an element that potassium decays into, making it a viable alternative to carbon-14 dating. The most common element in this group is found in 0.94% of the atmosphere. For 10 points, identify this group with a full octet that contains xenon, radon, helium, and argon.
